...late great German, Robert Koch (1843-1910), who with the late great Louis Pasteur (1822-95) gave medicine its modern turn and who lived long enough to win a Nobel Prize (1905),* discovered the tuberculosis bacillus. It is often called Koch's bacillus. One of Koch's and Pasteur's early disciples in the new medicine was young Léon Charles Albert Calmette (born 1863, at Nice). He began to practice medicine in Paris as their discoveries and technique were beginning to spread. He was then 23 and amenable to military service, like every young Frenchman after the Franco-German...
Continuing the researches of his great preceptors, Dr. Calmette with his associate C. Guérin, a veterinary surgeon, discovered that the descendants of the tuberculosis bacillus, bred for many generations in ox bile and glycerine, lost their virulency but could establish immunity in young animals against potent tuberculosis germs. In their experience the vaccine must be fed to an infant who has been exposed to the disease during its first ten days of life. Later it may be given hypodermically. It is powerless to cure, but has undoubtedly prevented tuberculosis...

Only woman member of the National Academy of Sciences, Dr. Sabin directs the testing of chemical substances isolated from the tubercule bacillus to discover their separate effects in order to analyze each factor of the disease itself...

...potato was more significant than the money. After biologists had fooled around with the tuberculosis bacillus for almost 50 years, they had developed two standard methods of discovering the bacilli in sputum. One was to stain a smear with dyes and search for the germs with a microscope. That was crude and inaccurate. The other was to inject suspected sputum into guinea pigs, creatures unusually susceptible to tuberculosis. That was slow and expensive. A quicker, surer method of diagnosis was needed...
